From 25 March 2024.
PS: "European Sleeper is also planning a winter night train between Amsterdam and the French Alps, as well as an EU-backed Amsterdam-Barcelona service launching in 2025. More sleeping cars should increase comfort and the travel experience, it said."
Bikes are carried on the European Sleeper for €19. They are carried in a large bike compartment in the seats car at one end of the train.

Will this be the same to Prague?
I've been doing dummy bookings for the summer as far as Prague with a bike and the web site will let you do it.
I've just asked about the sleeper compartments:
Q: Is it possible to book a sleeper for two people with no-one else sharing it?
A: yes thats possible, While making your booking, choose for the option "double" than the compartment is just for the 2 of you

No aging treatment can greatly alter the stiffness of a frame. only really the yield point, ie. when the deformations become plastic in nature. Normally frames age ~80-90% in a few weeks ie. in the boat from Taiwan, but this does depend on the ambient temperature.

Re: Just how long will it take to turn this ship around?
Yes, China has a lot of reserves and provides much of the current (!) supply. But there are
alternatives, as in the Forbes article which you cited. Those alternatives place a powerful (!) limit on China's control.
And lots of people saying the same thing doesn't make anything more or less true.

Re: Schengen Visa accommodation bookings when touring.

And as the Forbes article says:simonineaston wrote: ↑15 Apr 2024, 10:51amQuote from article in Forbes - see here and another article here…According to a study from the prestigious Brooking’s Institution, China presently produces some 60% of the world’s rare earth elements and processes 85% of them.
But if Beijing too actively, severely, and frequently denies users these vital materials, it is a good bet that the developed west and Japan will cultivate other sources and develop refining techniques acceptable to their more environmentally sensitive dispositions.
Nowhere near monopoly control.

And why are they assumed to be made of some sort of stainless steel?

Will be riding in and around East Riding of Yorkshire cycle paths disused railway tracks and road .
On the one hand full suspension for comfort especially with current potholes situation but also can be sluggish and heavy riding.
A gravel bike which are new to me and do you go flat bar / drop bars along with single drive train vs dual ring .
I’m bothered about stiff neck from drops but better areodynamics in head wind .
Thoughts or suggestions welcomed.
Ps currently riding hard tail for commute
Willing to spend upto £2000
Today I got the chance to go on a group road ride , first time on a road bike in 30 years lol
A Viking road master 700 by 25c 34/50 11-32 small frame , fit me like a glove ,
Managed 60km at a steady pace mainly head wind as well

Re: Techniques for braking on steep descents
"Tandem Braking":

As well drag brakes it has lots on slow and fast descending, and some physics, and some data (!), much of which is also relevant to lonely bikes.

Re: Take These (Supply) Chains from My Heart
The industry has made it very clear what differences they think this will make. They're asking for more efficient and fairer checking processes, and sensible periods of notice before implementation.
And, as always, please take the opportunity to mention the positives...
